My girls get excited for these for their summer work. They feel more confident in math after their first workbooks, so I am continuing to use them to supplement ay home what they are studying in school. These workbooks made an especially big difference for my oldest who has struggled in math.Excellent.This is an excellent book just for the introduction that shows you how to teach your kids to muliply in a week!Very useful. Thank you.Good bookI had been helping my 9 year old granddaughter with math with some success, however, it became much easier for her and for me once we got this book. It provides the structure and (sometimes) the tricks to master math at this grade level. The worksheets are excellent. My granddaughter now finishes her in class assignments quickly with few errors. I highly recommend this book.My Grade 4 child's mental sums capacity has improved greatly within 2 weeks of daily practicing the workbook. I highly recommend.This is an excellent source to compliment the math that's going on in schools right now. It breaks concepts down in simple, manageable, and tangible sequences. As an educator for the last 10 years, this is a great source for your child!The exercises were fun but I do recommend the parent or facilitator read it before to understand them before sitting with the child.John Mighton's Math workbooks take a different approach to learning and teaching math.....My son's math skills have improved and we will continue to use these......found amazon's prices to be comparable to other sites and I was thrilled to get them delivered so quickly.....
